And would you like it to be proven?But the statement "the waveguides in Gedlee loudspeakers could be improved by employing a better mouth flare with a more gradual change of curvature." is not proven by the data. If the waveguide is allowed to get larger then yes, this would be true, but given the physical constraints that I stated, it is not clear that it is true.
But I agree with you that it is not. Of course it is not.

If you want to prove it then yes, I'd like to see it, but otherwise I think we agree that you did not have data to support your statement.
Your polar plots shown before do look very good and I agree that the DI would be smooth in this case even with such a low crossover point, so on this claim I can now agree - for that specific case. But many horns/waveguide do exhibit a non-smooth fall in DI with frequency, this is common knowledge. That we can now have waveguides that don't do this is great. Congratulations. It opens up some previously untenable designs.

You are very tough but I appreciate that. Yes, in that case we agree that I don't have data to support my statementIf you want to prove it then yes, I'd like to see it, but otherwise I think we agree that you did not have data to support your statement.

Looks like I just scored a pair of BA-750 drivers, except it's the version with 1.4" exit.
At least 6 different diaphragm kits are available for this driver.
For the price of a single dome tweeter, there is not much to lose.

Hi Ro808,
The more accurate translation of the saying is: "The farrier's horse walks without shoes", the farrier not having time to put horseshoes his own horse(s).
Kindest regards,

As in: a blacksmith is a smith who works with iron and may know s..t about horses?
We have one that roughly translates as: ”Cobbler, stick to your last."

OK, I think I get it now. So this would be better I suppose...? (Just a quick sketch.)... Well, the further parts of the diaphragm will be out of phase with the center since the sound has further to travel. You'll get cancellation as wavelengths get shorter and more out of phase.

Ah, that is the word! In Czech we use the same word for a (black)smith or a farrier...The more accurate translation of the saying is: "The farrier's horse walks without shoes"...

Yep, I got that by now
Mabat,Ath 4.5.0 has been released
First - the script files ARE NOT BACKWARD COMPATIBLE.
The possibilities your scripts open up for designing horns for specific coverage patterns are incredible!
As the original thread starter, you may update your original post as you wish, including the new release there would be helpful, as this post will become hard to find fairly soon.
You might also highlight some of the details you have learned since the release.
In reviewing the thread, IIRC, #666 was the first to show measured results confirming the validity of the polar simulations, links to other posts that prove how well the simulations work would be useful.
Thanks for all the work!

I would like to but it seems I can't edit the first post anymoreAs the original thread starter, you may update your original post as you wish, including the new release there would be helpful, as this post will become hard to find fairly soon.
Thanks.
Edit: Oh, now the "Edit" button appeared. I sware it was not there before.

Here's Tymphany's patent, fwiw.

Nah, it doesn't work. I would have to contact administrator... Can't touch the attachments anymore.Oh, now the "Edit" button appeared. I sware it was not there before.

You can put a link in the OP (as you already did..)to the new attachment, and edit your misspelling of "design" ;^).I know. It's funny, it lets you edit the first post for 30 minutes after you posted somewhere else. You can't modify the attachments however.

If I'm reading that correctly, they're patenting a method for the alignment of the phase plug during assembly?Here's Tymphany's patent, fwiw.
The phase plug itself looks to be of a conventional circumferential slot design.Possibly, I haven't read it thoroughly yet. The phase plug channels - though nothing special wrt the design - grabbed my attention.
